Isolated danger zones occur on steep shady ridgeline slopes
Avalanche danger above 1800m is moderate, below that altitude danger is low. Freshly generated snowdrift accumulations can in some places be triggered by one sole skier as a slab avalanche. Releases tend to be small-sized. Danger zones occur esp. near ridgelines, behind protruberances in the landscape and in gullies and bowls, usually they are easy to recognize. On very steep shady slopes, weak layers can fracture and be swept along. Caution urged esp. at entry points into very steep gullies and little skied-on north-facing slopes. On extremely steep slopes, small loose-snow avalanches can be expected. Isolated small naturally triggered glide-snow avalanches are possible.
The fresh fallen snow (20-30cm) was deposited above 1800-2000m on an often loosely-packed surface. Moderate-velocity winds transported the fresh snow to ridgeline zones. In places the surface hoar was blanketed. The old snowpack fundament on steep shady slopes at high altitudes is expansively metamorphosed. On sunny slopes the layering of the below-average snowpack is stable, except for small superficial loose-snow avalanches. Gliding snow over smooth ground is observed only rarely.
Residual clouds in the Northern Alps will disperse in the morning, elsewhere there will be sunshine and good visibility. Winds light. At 2000m: between -9 and -3 degrees; at 3000m: -7 degrees.
No significant change in danger levels anticipated
